How we handle commercial air conditioning in Adelphi
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we’re not assessors, but we prepare systems for inspection and act on what the report finds. The work covers server and comms room cooling, ceiling cassettes and VRF systems, and the jobs we see most are TM44 recommendations that need acting on and older systems on refrigerants that are getting scarcer.
In Adelphi, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the records and tell you what’s due.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Your questions about commercial air conditioning in Adelphi
Do you cover Adelphi for commercial air conditioning?
Yes. Adelphi is one of the places we cover. Just ring 07833 053749 or use the quote form with a few details.
Is planning permission needed for air conditioning in Adelphi?
The answer turns on the property and where the outdoor unit would sit. The Adelphi Conservation Area takes in the middle of Adelphi. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to Westminster council, which is normally the planning authority for Adelphi when it matters.
What are the F-gas responsibilities for commercial air conditioning?
For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. The intervals are at least yearly from 5 to under 50 tCO2e, and 6-monthly from 50 to under 500 tCO2e, and we can handle both.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Looking after it afterwards
How well a system lasts depends on use and care. We suggest:
- Budget for replacing ageing plant
- Diary TM44 inspections in advance
- Involve us at the planning stage of a refurbishment
Should anything seem off after handover, phone us on 07833 053749, or email if that’s easier and we’ll look into it. There’s a 24/7 emergency line for breakdowns.
Planned maintenance is the best way to keep a commercial system healthy. We agree the visits and the price with your quote.
What affects the cost of commercial air conditioning
The price is fixed before any work begins. It takes into account:
- The brand, model and parts involved
- How far the pipework has to run, and where
- How easy the units are to reach
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.
Helping us quote
You don’t need the technical terms. Just send:
- The make and model of the system, from the label
- The remote or wall controller showing any error
- Where the property is and what kind of building it is
Published ranges are a starting point; the quote is built on your property, because every property is different. After a look at the job, by pictures or a survey, the price is fixed. To get going, phone 07833 053749.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. From there, the work takes as long as the site and the system need, from a short install to a phased project planned around opening hours. The more we can see beforehand, the smoother the visit to Adelphi will be.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Preparing for the visit
- Let us know where the consumer unit is
- Mention any managing agent or landlord rules we need to follow
- Plan for pets to be kept clear during the visit
How to get a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Before you call an engineer
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

What commercial work looks like in Adelphi
Food Standards Agency records list about 4,261 cafés, restaurants and staff canteens, about 243 hotels and guest houses and about 83 schools and colleges within about 1.5 miles of central Adelphi. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. About 41% of homes in and around Adelphi were built before 1919, according to VOA council tax data, and about 94% of households live in flats, according to the last census (2021). In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
If you look after a church or hall such as Savoy Chapel, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents. For a school like St Clement Danes CofE Primary School, air conditioning work is best done out of term.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
